HRT BLANKET DUMP TANK PRESSURE

Description

In changing the dumping program for the HRT, it is possible that the entire contents of the reactor will flow into the blanket dump tanks. This study investigates whether the resulting dum system pressure exceeds the allowable limit. For the case of a dump of the entire contents of the HRT high pressure system, commencing two minutes after shutdown from an operating power of 5 Mw and with an average fuel temperature of 280 deg C, into the blanket dump tanks, the resulting maximum presure was calculated to be about 375 psia. This maximum pressure which will occur about six ...

This maximum pressure which will occur about six minutes after the start of the dump, is well below the permissible limit of about 500 psia. (auth)
